Using Liquibase with Firebird

  5. How to Apply Your Liquibase Pro License Key – If you use Liquibase Pro, activate your license.

Install drivers

To use Liquibase and Firebird, you need the JDBC driver JAR file (Maven download).

The latest version of Liquibase has a pre-installed driver for this database in the liquibase/internal/lib directory, so you don't need to install it yourself.

If you use Maven, you must include the driver JAR as a dependency in your pom.xml file.


Test your connection

  1. Ensure your Firebird database is configured. See the Firebird Quickstart Guide for more information.
  2. Specify the database URL in the file (defaults file), along with other properties you want to set a default value for. Liquibase does not parse the URL. You can either specify the full database connection string or specify the URL using your database's standard JDBC format:
  3. url: jdbc:firebirdsql://localhost:3050//firebird/data/testdb

    Tip: To apply a Liquibase Pro key to your project, add the following property to the Liquibase properties file: licenseKey: <paste code here>

  1. Create a text file called changelog (.xml, .sql, .json, or .yaml) in your project directory and add a changeset.
  2. If you already created a changelog using the init project command, you can use that instead of creating a new file. When adding onto an existing changelog, be sure to only add the changeset and to not duplicate the changelog header.

    XML example
    <?xml version="1.0" encoding="UTF-8"?>
        <changeSet id="1" author="Liquibase">
            <createTable tableName="test_table">
                <column name="test_id" type="int">
                    <constraints primaryKey="true"/>
                <column name="test_column" type="varchar"/>
    SQL example
    -- liquibase formatted sql
    -- changeset liquibase:1
    CREATE TABLE test_table (test_id INT, test_column VARCHAR(255), PRIMARY KEY (test_id))

    Tip: Formatted SQL changelogs generated from Liquibase versions before 4.2 might cause issues because of the lack of space after a double dash ( -- ). To fix this, add a space after the double dash. For example: -- liquibase formatted sql instead of --liquibase formatted sql and -- changeset myname:create-table instead of --changeset myname:create-table.

    YAML example
       - changeSet:
           id: 1
           author: Liquibase
           - createTable:
               tableName: test_table
               - column:
                   name: test_column
                   type: INT
                       primaryKey:  true
                       nullable:  false
    JSON example
      "databaseChangeLog": [
          "changeSet": {
            "id": "1",
            "author": "Liquibase",
            "changes": [
                "createTable": {
                  "tableName": "test_table",
                  "columns": [
                      "column": {
                        "name": "test_column",
                        "type": "INT",
                        "constraints": {
                          "primaryKey": true,
                          "nullable": false
  3. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful:
  4. liquibase status --username=test --password=test --changelog-file=<changelog.xml>

    Note: You can specify arguments in the CLI or keep them in the Liquibase properties file.

    If your connection is successful, you'll see a message like this:

    4 changesets have not been applied to <your_jdbc_url>
    Liquibase command 'status' was executed successfully.
  5. Inspect the SQL with the update-sql command. Then make changes to your database with the update command.
  6. liquibase update-sql --changelog-file=<changelog.xml>
    liquibase update --changelog-file=<changelog.xml>

    If your update is successful, Liquibase runs each changeset and displays a summary message ending with:

    Liquibase: Update has been successful.
    Liquibase command 'update' was executed successfully.
  7. From a database UI tool, ensure that your database contains the test_table you added along with the DATABASECHANGELOG table and DATABASECHANGELOGLOCK table.

Now you're ready to start making deployments with Liquibase!

If you run the update command to deploy your changesets and receive the error message related to the DATABASECHANGELOGLOCK table issue, manually create the DATABASECHANGELOGLOCK table using SMALLINT type instead of BOOLEAN:
